           Summary: Crash while compiling minimal boost::regex_match
                    program.
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++

clang++ crashes while instantiating the boost::regex_match template for a
minimal example. The code is as followed (preprocessed example is attached):
----
#include <boost/regex.hpp>

int main()
{
    return boost::regex_match("lalabc", boost::regex(".*abc")) ? 0 : 1;
}
----

clang crashes with the following output:
